Failed to set the 'value' property on 'HTMLInputElement': This input element accepts a filename, which may only be programmatically set to the empty string

.NET  MVC含上传表单提交时，js报错。Failed to set the 'value' property on 'HTMLInputElement': This input element accepts a filename, which may only be programmatically set to the empty string

解决方案:

jquery:

var fileHook = {
get: function (elem) {
return this.value;
},
set: function (elem, value) {
return this.value = value;
}
}
$.valHooks["file"] = fileHook;
if (!hooks || !("set" in hooks) || hooks.set(this, val, "value") === undefined) {
this.value = val;
}

红色js前面加这句即可！
